Pool Startup New Water?

[atkinson40]

The filter grids that I bought some time ago are FS-2005, 60 sq foot. How do I know how much DE to add? The amount I add always seem to clog up the grids and reduce the flow. One top of the grids is broken so I will buy a new set on Amazon and replace before adding DE.

Could I use pucks to bring the stabilizer level up?

[PoolDoc]

Yes.

Dichlor is 55% chlorine, 50% stabilizer; trichlor is 90% chlorine, 55% stabilizer.

(Yes, I know those %'s don't add up right. Long history behind that, which I'm not going to explain here. Trust me, it will work out the way the %'s imply)

Thanks PoolDoc

My tabs say Triclor-S-Triazinetrione. I'll start chlorinating the pool with them and watch the CYA very closely. I'll check the PH. I have acid. I believe Borax was the agent recommended by you to raise the PH if need be.

I'll review my pool chemistry.

. . . one of the names for trichlor.
